BAD SERVICE

I've had the worst experience ever at the Mc Donald's Park Town Branch, everytime I buy food there my order has to come back wrong and the Manager Edwin does nothing about it today I had to sit yet again on a phone being told to wait and hold and still I didn't get service if nothing is going to be done at that branch why don't you guys just close it down I always order the same thing Spicy Foldover with no onion because I'm allergic but as soon as my food arrives it has onions this is now the third time this has happened I am very disappointed with the service there and I will not be ordering there ever again.
